int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(Parcel, int),
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR bit.
| Returns | |
|---|---|
int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. |
MediaFormat getFormat ()
Gets the MediaFormat of the track. If the format is
unknown or could not be determined, null is returned.
| Returns | |
|---|---|
MediaFormat |
|
String getLanguage ()
Gets the language code of the track.
| Returns | |
|---|---|
String |
a language code in either way of ISO-639-1 or ISO-639-2. When the language is unknown or could not be determined, ISO-639-2 language code, "und", is returned. |
int getTrackType ()
Gets the track type.
| Returns | |
|---|---|
int |
TrackType which indicates if the track is video, audio, timed text. |
String toString ()
Returns a string representation of the object. In general, the
toString method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
| Returns | |
|---|---|
String |
a string representation of the object. |
void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
dest |
Parcel:
The Parcel in which the object should be written. |
flags |
int:
Additional flags about how the object should be written.
May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
